Britain must stop financing fossil fuel projects abroad by 2021 as it undermines the nation’s efforts to combat climate change, a report by lawmakers said on Monday.

The report, which targets financial support provided by the UK Export Finance (UKEF) agency, was published as Britain debates plans to set tougher climate goals and move towards a net zero emissions target by 2050, Reuters wrote.

“The government claims that the UK is a world leader on tackling climate change,” said Mary Creagh, chair of the Environment Audit Committee, commenting on the report published by the committee.

“But behind the scenes the UK’s export finance schemes are handing out billions of pounds of taxpayers money to develop fossil fuel projects in poorer countries,” she said.

In five years from April 2013, UKEF allocated 96 percent of its energy sector support, or 2.5 billion pounds, to support fossil fuel projects, the report said.

The report said this was incompatible with Britain’s efforts to reduce greenhouse gases and also carried risks for taxpayers.

Companies could be left with stranded assets as tougher emission reduction targets discourage fossil fuel use and as renewable energy becomes cheaper.

The Paris climate agreement, adopted by almost 200 nations in 2015, set a long-term goal to limit global warming to ‘well below’ a rise of 2°C above pre-industrial times while striving towards a tougher goal of just 1.5°C.
